application filed July 5, This invention relates to new and usefulimprovements in a massaging''machinea @ne object of the invention is toprovide an exercising or massaging apparatus, specially designed for usein exercising-thc trunk and limbs of the human body ae an :iid in thetreatment oi disease and for the purpose of reducing the weight of thepatient. i

Another object of the invention is to provide an apparatus of thecharacter described by which the body may be exercised by a belt orban-d which is adapted to ,surround the trunk or limbs of the patientand which is connected to a yioldable oscillating anchor so that theshock or vibration imparted to the body members Will oe somewhatrelieved so as not to be too severe, or iniorious.

A further feature of the invention is to provide a device of thecharacter described including means whereby the range of oscillatorymovement of the anchor, to which the belt is attached, may be varied soasA to regulate operation of the beit.

A stili further feature of the invention resides in a novel type ofcabinet ing and partially enclosing the operative mechanism.

With the above and other objects inlview the invention has particularrelation to certain novel features of .consti-notion, opera# Ation andarrangementof parts, anexamplef of which is given'in this specificationand iliustrated in the accompanying drawings, wherein zv Figure l showsa vertical 'sectional view of the device.

a tubular housing 2, preferably of about onchalf the diameter oi. thebase l. The bousing has a cap .like cover 3 ittedonto the topthereof. l

l/V'ithiu the housing is asuitable suo port L3.- having'a lateralspindle 5 on which the large gear (i rotates. Mounted on the base l,outside. of the housing 2 there -i's an electric motor 7 whose shaft 8has a small wheel 9 fixed the Eon and in mesh with. the gear 6. TheSupport 4 also carries a lateral` spindle l on which the connectingrodil is pivoted. The lower end of this rod has slot l2 and the gear 6. hasan eccentric wristpin 13 which has ia bearing in the bearing block i4,mounted to slide'in said slot 12.

There is a vertical rocker shaft 15, whose lower end Works in thebearing 16 inthe top of the support i, and whose upper end is fittedthrough the bearing- 17 in the cover 3. This shaft has a limitedvertical movement in said bearings.` 'Fixed to the shaft there is anoscillating arm 1,8 Whose outer end Works through the bearing 19. Thisbearing is'mounted to rotate on ay vertical axis in the bearing block20. This block 20 is slidably mounted in an oblong length#y wise siot 2lmeeting rod 1i,7 and moves buck and fo therein as said rod oseillates.
